Pregnancy twins, pregnancy week 3 symptoms, the pregnancy of twins.
What is the size of the fetus 3 weeks pregnant?
In the third week of pregnancy, your fetus is too small to recognize it with the naked eye, although it grows at an extraordinary speed.
At this point, your embryo is a sphere of cells that can match the size of the head of a needle.
The shape of your fetus now resembles a bubble and not a baby but this will change later.
Twins Pregnancy – How likely are you to have twins?
Many people are wondering in the third week of pregnancy what their chances are for the pregnancy of twins.
Twins pregnancy usually occurs when one or more eggs are released from the ovary or ovaries.
The egg can be fertilized by two separate seeds which will bring twins.
Another case is when one egg fertilized by one seed is divided into two at the time of initial division and creates identical twins.
When there are identical twins, their chromosomal structure is the same and therefore they will be of the same sex with the same physical characteristics.
Sometimes different combinations are possible, such as a trio.
A triplet pregnancy can happen, for example, if two or more eggs are fertilized or two eggs are fertilized and one of them is divided into two.
The human body has endless possibilities and the whole process is amazing in itself.
If you have a family history of twins you are more likely to have twins, but not necessarily.
At the same time, twin pregnancies are becoming increasingly prevalent due to fertility and reproduction technologies.
Growth and development of the fetus at 3 weeks of pregnancy
By the third week of pregnancy, very few women are aware of the fact that they are pregnant.
However, your fetus is already beginning to grow inside you.
Currently, the embryo consists of a ball of cells that multiplies and expands itself at tremendous speed, but it still has no human form and does not exceed 0.1-0.2 mm.
The resulting fetus is actually a combination of 23 chromosomes of you and your partner.
Three days after fertilization the embryo cell begins to form.
In the third week of pregnancy, amniotic fluid begins to collect around the cell ball that is actually the embryo.
Amniotic fluid will protect and cover your fetus during the nine months of pregnancy.
During week 3, the fetal cell system is implanted into your uterus and uses the blood vessels in the uterus.
The placenta develops only after the fourth week, but until that happens, your fetus gets all the nutrients it needs from your uterus and from you.
Your Body in the fourth Pregnancy Week
During this period, many internal physiological changes occur in your body.
Many women will not understand these changes until a few weeks.
When the egg reaches the uterus, it finds a corner of the uterine mucosa and is implanted there, when the capillaries of the uterine fibroids surround it and it begins to receive nourishment from the mother’s body.
Sometimes there can be bleeding and rooting which is the weakest and minor bleeding.
Many women sometimes interpret this bleeding as a weak menstruation or as the beginning of menstruation.
This bleeding is caused by the implantation of the egg into the lining of the uterus but is usually quite a few drops.
Bleeding can sometimes occur as brown or pink stains on top of the petticoat or by wiping.
Your diet during early pregnancy
Your diet during the first weeks of pregnancy is essential and it is important that you eat in a healthy way.
It is also important that you adopt a healthy and active lifestyle and even continue your physical activity as long as your pregnancy is normal.
It is recommended to enrich your diet with fruits, vegetables, legumes and grains that will give your body the nutrients it needs.
At the beginning of pregnancy, your body needs proper nutrition to produce energy and support an additional life system within your body.
Many women experience significant physical fatigue and energy levels drop.
This happens because the body works overtime to allow the fetus to grow and get what it needs.
If you feel tired, do not burden yourself, try to shorten your working hours if you can or go to bed earlier so as not to exhaust the body that is currently in need of energy.
Changes in the body at the beginning of pregnancy
By week 3 you are probably not aware of significant changes in your body.
Sometimes you will find that you are slightly swollen as after ovulation and as you continue your pregnancy you will find that the waistline expands slightly.
The chest is usually more sensitive and sometimes even slightly enlarged.
Weight gain in pregnancy
We recommend checking your weight once a week for the protocol.
Many women worry about gaining weight during pregnancy but remember that it is a natural and healthy process that all of them experience.
Most women will be between 8-15 kg during pregnancy and even more if they carry twins.
Most of this weight is divided between the placenta, the uterus, amniotic fluid, fluid in the tissues and fetus.
Due to the increased effort of the body, the appetite opens and in many cases, you will be hungry and the body will require what it needs.
However, take this time to appreciate and enjoy these amazing changes taking place in your body and remember that every pound you gained is a pound that will support your baby during pregnancy.
Women with lean build-up, sometimes gain a lot more weight, sometimes even 20 or 30 pounds.
You should be monitored by a dietician if your weight gain is very high.
A positive pregnancy test at 3 weeks pregnant
If you are in the process of getting pregnant, you are probably full of excitement and anticipation,
But unfortunately, there will not be a positive answer yet at this time.
A positive response to a pregnancy test will usually come only a day or two after the delay in the cycle.
That it comes out, at least 12 days after the date of ovulation or fertilization, so it is better to wait for the arrival of menstruation and only then check.
Even the most sensitive tests and tests that promise “answer 4-5 days before the lateness of the period” will not identify pregnancy during this period.
Wait for a week – 10 more days.
On the reliability of home pregnancy tests that identify pregnancy before overdue – you should read the following article if you plan to do a home test before the lateness date.
Pregnancy and Your health
If you are trying to get pregnant, now is the time to give up your glass of wine and avoid drinking alcohol and smoking.
If you take any medication regularly, consult your doctor if you know you are trying to get pregnant.
Also, psychiatric drugs such as antidepressant pills in pregnancy or pregnant ritalin are recommended to stop.
And again, before you make any change, please consult your doctor about it.
Consider relaxing ceremonies during pregnancy.
Meditation is a wonderful and easy way to relax and benefit both you and the fetus.
If you find yourself vitriolic every now and then, grapefruit juice can be refreshing and excellent and energetic.
It is recommended that you give up coffee and caffeine even though they will not have serious effects on your baby.
If you have decided to become pregnant, it is important that you begin to adopt healthier habits for your body.
Eat a varied diet of vegetables, iron-rich foods, and avoid junk food and fried and fatty foods.
